Hi ! I'm not sure if it's the right list but I hope someone can help me !
I am setting up a SIP VoIP gateway using Asterisk and a Digium E100P card plugged on a Swisscom PRI ISDN. I setup my card using ccs framing, hdb3 coding with crc4 checking and euroisdn switch type. Everything works well with incoming calls, my Grandstream SIP phones ring and answer calls, show right CID and so on, but when dialling out from SIP to PSTN, it looks like it works, asterisk shows the correct things, says number is ringing, but nothing happens on the remote PSTN phone. Asterisk has no "tone zone" for Switzerland, means no DTMF info. I tried several other countries DTMF settings with no success thinking it might be the cause. Any suggestion ? Do you know Swisscom's DTMF settings ? Similar to other countries ?? Thanks. ---------------------------------------------- [EMAIL PROTECTED] Maillist-Archive: http://www.mail-archive.com/swinog%40swinog.ch/
